ADM606 Rackmount Multifunction Ratemeter/Scaler

ADM606 Rackmount Multifunction Ratemeter/Scaler

Description

The ADM606 is a microprocessor controlled digital ratemeter, designed to power, control and process data from various types of CANBERRA radiation detectors. The ADM606 can operate with both area and process monitoring detectors for measurement of many types of low and high intensity radioactivity. The area monitoring detectors are designed for open area detection of gamma or neutron radiation. Process monitoring detectors detect alpha/beta/gamma activity and are designed to mount in fluid or gas flow streams such as ventilation ducts, stacks or liquid piping systems.

The ADM606 is designed to take full advantage of the features of the CANBERRA "SMART" detector series, it also can operate with conventional detectors, or with a combination of conventional and "SMART" detectors. When coupled with the "SMART" detectors, the ADM606 interrogates each connected probe to determine the detector type and calibration constants, then automatically sets the display of measurement type and units for that measurement channel. This feature allows for quick detector swapout, and permits factory calibration of detectors rather than time consuming in-field calibration of each monitoring station.

The ADM606 can be installed as one of a total of three units mounted in a 19 in. wide by 7 in. tall CR600 NIM style rack. The ADM is interfaced directly to a Rear Termination Panel Assembly, CR600TP. The CR600TP and optional CR600CIP, Customer Interface Panel, provides terminal blocks connections to relay contacts, communication ports, and analog and digital inputs/outputs.

The ADM606 provides the following user interface features: 2 lines x 20 characters vacuum fluorescent display, six button membrane switch keypad, three position key switch, four LED indicators, and a RS-232 serial port.

The ADM606 also provides the following control and communication circuitry with connections made through the Termination panel, CR600TP: Eight Single Pole Double Throw (SPDT) relays.

The ADM606 allows configuration of the alarms to be latching or non-latching and to configure the alarm relays as normally energized (de-energized on alarm, failsafe) or normally de-energized (energize on alarm).

In latching mode, the alarm indicators continue to indicate alarm until after the rate drops below the alarm setpoint and the operator has pressed the Reset button. In non-latching (or tracking mode), the alarm indicators automatically reset when the rate drops below the alarm setpoint.

When used in the local configuration, ADM606 supports CANBERRA's unique Time-to-Count technology and LED-based gain stabilization for scintillation detectors for enhanced RMS performance.

The ADM606 can be used in a remote configuration in a control room where it can interface with other field-installed ratemeters such as the iR7040, ADM606M, ADM616 or Tritium Monitors such as the TAM100D/T100DSI, or TAM73D/T73DSI.

Features

Connectivity to both area and process monitor type probes – Alpha, Beta, Gamma and Neutron detection – low and high intensity radiation fields

Description

The MDN455EPA/MDNR455EPA matched pairs consist of a beta/gamma scintillation detector coupled to a PA300E preamplifier. While the MDN455EPA model utilizes a straight cable connection at the back of the detector, the MDNR455EPA utilizes a right angle connection for use in tight spaces. These factory matched and calibrated detector pairs simplify deployment in new or existing systems by eliminating the need for calibration/matching during installation.

The MDN455E beta scintillation detector consists of a plastic beta scintillator and a non-hygroscopic gamma scintillator optically coupled to a photomultiplier (PM) tube via a Lucite light pipe. A reference Light Emitting Diode (LED) and a temperature sensor are imbedded in the Lucite pipe.

This detector operates in conjunction with a preamplifier, Model PA300E. The preamplifier contains circuitry that compares the LED pulses with a reference to provide closed loop feedback for automatic gain compensation. The PA300E also amplifies and shapes the detector output signal in order to provide digital pulses to the remotely located ratemeter. Procurement of matched detector/preamplifier sets is recommended to simplify field maintenance and system support. See ordering information for details.

The MDN455EPA/MDNR455EPA can be connected to multifunction control and display unit such as iR7040, ADM606, and ADM616.
